is rigidly secured. Upon either side of this At the inner end of thegrain-platform'and frame arc-shaped gear-racks p p are fastened, inproximity to the edge of the canvas is arranged a transferring-rollerL", the position of the roller being a little above that of theplatform-canvas, but not so high as the binder deck or table. The innerside of the deck E is inclined or concaved, as shown in Fig. 5,

and its edge is arranged close to the periphery of the roller L", theobject of this arrangement being to permit the roller as it receives thegrain from the platform-canvas to elevate and transfer it to theconcaved or inclined portion of the deck, whence it is taken by afeeding device and carried upward and for ward onto the main body of thedeck within reach of the packers of the binder.

As before stated, the feeding, packing, separating, binding, andejecting devices areall carried by or with the movable binder-table E.The binder-frame proper consists ofthe usual standard J having a tubulararm J, overhanging the deckand carrying the usual or any preferredknotting' devices, the breastplate, and the combined separator andejector. This frame occupies a position about 0on trally of the width ofthe table and is secured to the latter so as to be movable therewith.Secured to the standard J and projecting on either side of the same soas to extend clear across the width of the binding-table, and preferablyspanning the entire space between the inner end of the platform-canvasand the main wheel-frame, is an end-board H, which board closes thefront end of the binding-receptacle and the grain-passage leadingthereto and also furnishes a support for part of the gearing whichdrives the reel, the feeding device, and the binder. Located at theouter edge of the binder-deck is a vertical guard or side board it,which board may be connected with the deck and the end board H andmovable therewith, or may be secured to the wheelframe in fixedposition. The board closes the outer side of the binding-receptacle nextto the main wheel, and prevents the bundles from being thrown againstthe wheel or entangled with any part of the gearing.

The mechanism for feeding the grain up the inclined part of the table Eonto the deck proper consists of a roller L, journaled at its front endin the end board H and at its rear end in a bracket S, depending fromthe overhead bar U, which in turn is secured at its front end to theboard I1 and has a supplemental support at or about the middle from theusual knotter' breast-plate I, as. clearly shown in Figs. 3 and 5. Thisbreast-plate, it will be understood is secured to and supported in theusual manner by the overhanging arm J of the binder-frame. Thefeed-roller is armed with teeth Z, arranged in rows longitudinally ofthe same, said teeth being curved or inclined in the reverse directionto the rotation of the roller, so as to clear themselves from the grain.As a further preventive of entanglement of the grain with the roller Iprovidea number of guards or strippers Z, these guards being made ofspring metal and se cured at their upper ends to the overhead bar U andextending down on theinner sideof the roller and having their freeendslying close to or hearing against the periphery of the plain portionof the roller. It is preferable to arrange these guards in pairs, onefor each set of teeth, as shown in Fig. 6, though this is by no meansessential. By supporting the roller in the manner above described, therear end of the grain-passage leading from the platform-canvas to thebinder-deck is left open at the rear, the object being to permit thepassage of grain of unusual length and to allow the adjustment of theroller with the bindertable.

The mechanism for packing, compressing, separating, and binding thegrain into bundles, herein illustrated, is of a type now well known inthe art and no particular novelty is claimed therein,excepting in so faras the binder-arm guard is concerned.

Referring more especially to Fig. 5, K denotes the needle or binder arm,0 the tripping compressor, and h h the vibrating packers, the latterbeing connected at their heel ends to a stationary support by means oflinks a a" and driven by cranks on the shaft d. In low-down binders theusual rigid guard extending from the back of the needle for the purposeof preventing the packers acting on the grain while the needle isencircling the bundle is impracticable, owing to thelow position of thebinding-table. I therefore dispense with this integral projection andprovideaseparate guard-arm preferably mounted on the same shaft as'theneedle and arranged to operate in conjunction therewith, so that as theneedle rises the guard will also rise and hold back the grain and as theneedle falls the guard will be depressed below the surface of the deck,as indicated in Fig. 16.

Referring to Figs. 15 and 16, K indicates the guard. It approximatesclosely the shape of the needle itself and is loosely pivoted on theneedle-shaft, so as to lie close alongside of the body of the needle.The connection between the arm and the shaft is made by means of aspring K one end of which is secured to the shaft, and the other end,after taking several turns around the shaft, engages with a pin on thearm, so as to tend constantly to raise and hold the arm in elevatedposition with its guard above the table, a lug?) being provided on oneside of the arm to contact with the under side of the table to limitthis movement. In order to depress the arm and hold its guard part downbelow the table when the needle is down, the latter is provi'ded with alug r1, projecting from the side next to the arm, which lug strikes thetop part of the arm as the needle recedes and forces it down and holdsit below the table. The point of the guard is coincident with the pointof the needle, the object being that, as the needle is positivelyraised,'the guard may follow in the rift in the grain caused by theentrance of the needle.

I will now describe the mechanism for discharging the bound bundles fromthe machine.

The letters a a denote the usual revolving binder-ejectors,theseejectors being rigid on the knotter-driving shaft and operating, so faras the action of the binder itself is concerned, in substantially thesame manner as in well-known machines of the present day.

T indicates a vertically-swinging bundledischarge fork or throw-off arm,the object of which is to take the bundles from the binder,

or, more properly speaking, from the ejectors, and throw them overtoward the rear of the machine in the manner hereinbefore referred to.This fork is mounted upon a bracket D, secured to the binder-table atits outer edge on the wheel side of the receptacle and near the rearcorner of the binder. Being mounted upon or secured to the binder-tableE, the forkis adjustable fore and aft with thebinder, and alwayspreserves a constant relation to the binding mechanism and to theejectors a. Projecting from the side of the fork next to thebinding-receptacle are tines 25, there being preferably two of thesetines, one located at the extreme end of the fork in front of thebinder-ejectors and the other in the rear of the ejectors at a pointfarther along its length. These tines stand in toward-thebinder-receptacle and are preferably curved, as indicated in Figs. 5 and10, so as to form a sort of cradle-like receptacle for the bundles, theend tine passing under and supporting the butt of the bundle and theother tine supporting the bundle about midway of its length andpreferably piercing it on the opposite side of the band, so as toprevent the bundle from sliding down the fork when the latter rises. Theaxis upon which the fork swings is sub stantially horizontal andtransverse to the binder-receptacle and is located preferably somewhatabove the level of the table. The particular manner of mounting andoperating the fork and the timing of the same with relation to thebinder-ejectors is an important feature of the invention and will now bedescribed.

The binder-ejectors a, although operating in substantially the samemanner as heretofore with relation to the binding-devices, arepreferably curved in the direction of their rotation, as represented inFigs. 3 and 5, or in an opposite direction to the curvature of thefork-tines, and the fork is operated from the shaft carrying theejectors, so as to start just as the ejectors in coming around to pushthe bundle out of the binder meet the tines If, so that the bundle islifted bodily out of the binder by the conjoint action of the twodevices, the binder-ejectors eifecting a clean separation of theoutgoing bundle from the gavel which follows it into the binder.

This concurrent movement of the two devices continues until the usualpause in the movement of the binder-ejectors, when, the bundle havingbeen completely separated from the gavel andlifted bodily from the placeof binding of starting the bundle and help it when assistance is mostneeded.

As before explained, the tines lie in substantially a horizontaldirection when the fork is in receiving position and they retain thisrelative position until the bundle has been discharged. It will beobvious, however, that it would not be possible to return the fork toproper receivingposition with the tines in this position. I thereforeprovide for turning the fork on its longitudinal axis as it starts toreturn to place, so that the tines go down end foremost until they reachthe place of binding, when the fork is rocked, so as to bring them inproper horizontal position. This is effected by the following mechanism:

Referring to Figs. 9 to 12, D denotes the bracket hereinbefore referredto and T an arm projecting from a short shaft journaled horizontally inthe same. The arm Tcarries a sleeve arranged transversely of its axis,and in this sleeve is j'ournaled the butt end of the fork T. g indicatesa dog projecting'radially from the end of the fork on one side of thesleeve, and g" a similar dog projecting from the fork at an angle ofabout ninety degrees from the dogg on the opposite side of the sleeve.,These two dogs, co-operating with camsand recesses on the face of thebracket D, presently to be described, serveto rock the fork on itslongitudinal axis, as above described. .h indicates a recess in the faceof the bracket D, into which the end of the dog g extends when the forkis down in receiving position, so that the side face of the dog is inposition to engage the plain surface h of the bracket in the risingmovement of the fork, which engagement prevents the rocking of the fork.At the opposite end of the plain surface it from the recess h" isanother recess h. The dog 9 projects from the opposite side of the forkfrom the tines t, and the weight of the bundle on the tines would rockthe shaft except for the plain surface 71/7 acting on the dog When,however, the fork has risen into position where the bundle leaves it,the dog 9'' comes opposite the recess h, when the resistance of thebundles turns thefork and the dog enters the recess andthe tines pointdownward. f is a springactuated switch-cam, onto which the opposite faceof the dog runs as the-fork recedes, and which holds the same with itstines pointing downward until the dog runs off the cam and enters againthe recess h. The spring j tion it stands opposite the recess h', readyto receive the dog g as it emerges from the recess on the return of thefork. The dog g is sleeved upon the square shank of the fork so as toslide but not to turn thereon. The cam f has a projecting flangef", theobject of which is to insure the passage of the dog 9 onto the cam inthe return movement of the fork and to prevent the dog from engaging thecam as the fork rises and cause it to engage the plain surface 72 Inorder to rock the fork positively so as to present the tines in properhorizontal position when the fork is down, a lug or shoulder g isarranged on the bracket D diametrically opposite the recess h", whichshoulder is engaged by the end dog g, causing the fork to rock, so thatthe dog 9 enters the recess h" and the tines to.lie flat, as in Fig. 5.

The gearing for operating the several mechanisms hereinbefore describedis as follows: Referring to Fig. 7, (1 denotes the line-shaft abovedescribed. This shaft drives the out ter-bar by means of the crank 1- onits front end and the pitman s, and the platform-canvas by means of thesprocket-wheel E on its rear end, over which is thrown the chain-belt Ewhich passes around the sprocket-wheel E on the inner roller K, and overthe similar wheel E on the rear end of the transferwheel L, which italso drives.

All the other parts of the machine are driven from the packer-shaft 01,mounted in bearings on the under side of the binder-table, whichpacker-shaft is, however, also operated from the line-shaft. Thepacker-shaft takes its rotation from the line-shaft by means of thegear-train b, b, and b, the wheel b being an idler journaled in abracket on the underside of the binder-table and serving to transmitmotion from the pinion b on the line-shaft to the gear I) on thepacker-shaft. As the packer-shaft is adjustable with the bindertable,the prime-pinion b is splined upon the line-shaft in a manner Wellunderstood, so as to preserve the relation of the gears in the variousadjustments. On its front end the packer-shaft carries a fixedsprocket-wheel d and a loose pinion b, there being a clutchconnectionbetween the two wheels so that the latter is driven intermittently bythe former which has a continuous rotation with the packer-shaft. Thesprocket-wheel d drives a pinion b mounted on a stud-shaft on the upperpart of the end board 11, from which wheel b the feeding-roller L isconstantly driven by means of intermediate gearing b and f. The reel Kis also driven from the wheel b by means of a tumbling-shaft connectionK The loose pinion b on the packer-shaft gears with a pinion f, mountedon a stud-shaft on the end-board H, which pinion is integral with asprocket-wheel f which drives the binder-operating shaft R by means of achain-belt thrown around said wheel f and the wheel R on the front endof the shaft just outside of the frame-standard men's? a pitman d,connecting the wheel R with a crank 01' on the shaft J As before stated,tl1e discharge-fork is operated in unison with and in a certain relationto the ejectors which are mounted on the binder-shaft B. To effect thisoperation the wheel R is provided with a rim 4, having a gear-segment bthereon. This gear-segment and rim control the operation of thedischargefork through the instrumentality of a shaft 0", mounted inbearings on the standard J and having a gear-pinion f at its outer endco-operating with the rim and segment, and a crank W at its lower endconnecting by means of a pitman T with the end of the fork-carrying armD by means of a swivelconnection u. The pinion f will preferably have asuitable delay-shoe acting on the rim 1" to hold theshaft r stationary,except at the proper time, and the gear-segment is arranged at suchpoint with relation to the position of the ejector-arms as to cause thero-' tation of the shaft 4" and the operation of the discharge-fork atthe time and for the purpose hereinbefore fully explained.

Having thus described the invention, what I claim, and desire to secure,is p 1. In a bundle discharging mechanism for binders, the combination,substantially as hereinbefore described, of the binder ejector, asupplemental discharger working in a plane at an angle to that of thebinder ejector, and mechanism for operating the discharger relative tothe ejector so that the bundle will be removed from the binder by thesimultaneous action of the two devices and discharged from the machinein a direction at an angle to the line of movement of the binderejector.
